Round-to-Square Valves and Square-to-Square Valves

Whether you refer to them as junk trap, trash extractor, reject or scavenger valves, our DSS  Round-to-Square and Square-to- Square Valves provide the innovative Guided Shear Gate Design to the toughest applications found in high-density cleaners (cyclones) and pneumatic conveying processes. 

A Knife Gate That Can Actually Cut

The key to the Guided Shear Gate design is the shearing tip and internal gate guides. From open to close the gate is guided the entire way removing any option to deflect when solids are encountered. Material is struck by the shearing tip, fractured and angled away, enabling zero leakage where the gate meets the primary seal.
